And the next thing you heard was... Men.

My grandmother.

Men.

This sort of frail, gentle voice.

And she started to unpick what was being transmitted to her.

Remember that line again was?

It's amazing to listen to.

Over 60 years later, listening to those tapes, I'm still on the edge of my seat.

And right at the end.

Almost every time it would be 100% correct.

It just was this feeling inside you that you get going, hang on, what?

When Jesse heard those broadcasts, his obvious question was, how did they do that?

Well, this is the question that I wanted to know.

For so long.

And there have been many, many theories.

I mean, they used to get letters in from listeners all the time.

There's this box of press clippings we found at the bottom of my grandma's closet, and we started going through these press clippings.

And there were wild theories, like little Morse code transmitters in their teeth.

I mean, one of the theories I quite liked was someone who wrote in saying there was a green man that ran between their shoulders.

And he knew this on authority because he also had a green man.
